Brief description

This collection contains nitrogen runoff data for an alternate furrow flood irrigation system. Data contains concentration and flow values, disaggregated by furrow type for irrigations 1, 2 and 4 of a single season. Chemical data includes pH, electrical conductivity (EC) and water temperature measured in situ, and nitrate—N (NO3—N), ammonium—N (NH4—N), urea—N and total dissolved N (TDN) measured from collected samples. Chemical sampling occurred at 30 minute intervals within irrigations. Flow data was measured at 30 second intervals. Data was performed at the Australian Cotton Research Institute (ACRI), Narrabri Australia.
Lineage: The field site at the Australian Cotton Research Institute (ACRI) had furrows ~130 m long at 1 m spacing, approximately 20 cm high. Soil was high shrink-swell, haplic, self-mulching medium Grey Vertosol. Data was collected approximately 5 m from end of furrow, with special care taken to avoid tail drain back-up contamination. Supply water measurements were taken from the head ditch immediately prior to syphon supplying given furrow.
Chemical data includes pH, electrical conductivity (EC) and water temperature measured in situ using a TPS Aqua-CP/A multi-probe, and nitrate—N (NO3—N), ammonium—N (NH4—N), urea—N and total dissolved N (TDN) measured from collected samples using an Alpkem Segmented Flow Analyser, Alpkem Corporation, Perstorp Analytical Co., Wilsonville, OR 97070 USA.
Flow data from individual furrows were collected using portable long-throated Replogle-Bos-Clemmens (RBC) flumes, installed prior to each irrigation event. VanEssen Baro Diver pressure sensors were used to measure water height in the flumes, from which flow was calculated.
